XPRBprobminim(String) Method |
Use setSense(BCLconstant.XPRB_MINIM) followed by lpOptimize and mipOptimize methods instead
Minimize a problem. This method selects and starts the
Xpress-Optimizer solution algorithm. The characters indicating the algorithm
choice may be combined where it makes sense, e.g. "dg". If the matrix loaded
in Xpress-Optimizer does not correspond to the current problem definition it
is regenerated automatically prior to the start of the algorithm.
Before solving a problem, the objective function must be selected with setObj().
Note that if you use an incomplete global search you should finish your program
with a call to the Xpress-Optimizer method XPRSprob.PostSolve()
(see Xpress-Optimizer manual for details) in order to remove all search tree
information that has been stored. Otherwise you may not be able to re-run your program.

Public Function minim (
alg As String
) As IntegerParameters
- alg String
- The string choice of solution algorithm. Possible values are:
- "p" – Use primal simplex algorithm.
- "d" – Use dual simplex algorithm.
- "b" – Use Newton-Barrier algorithm.
- "l" – Only solve the (relaxed) linear problem.
- "g" – Solve the global (MIP) problem.
- "" – No parameter, use the default setting (LP only).
Return Value
Int320 on success, 1 otherwise.
